' Application filed May I6, 1892.

To all whom it may concern:

Be it known that I, CHARLES S. KERSHAW, of Rome, in'the county of Oneidaand State of New York, have invented certain new and usedo herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to whichitappertains to make'and use the same, reference being had to theaccompanying drawings, andto the letters and figures of reference markedthereon, which form part of this specification.

My invention relates to an improvement in separable links adapted to beused in forming chains or cables and especially adapted for joiningchains or cables or effecting couplings in ropes or other similarconnections.

In the drawings which accompany and form a part of this specification,and in which similar letters and figures of reference refer tocorresponding parts in the several figures, Figure 1 shows a plan viewof the link. Fig. 2 shows an edge view. Fig. 3 shows an end View. Figs.4 and 5 show plan views from the inner side or engaging face of the twoparts of the link, the two being identical in form. Fig. 6 shows an edgeview of one part of the link, being the left-hand edge, as shown inFigs. 4 and 5. Fig. 7 shows an edge view, showing the opposite edge fromthat shown in Fig. 6, being the right-hand edge, as shown in Figs. 4 and5. Fig. 8 shows a section through the link, taken on either of lines ABof Fig. 1, the parts being slightly separated to better illustrate theconstruction. Fig. 9 shows a section taken on either of lines E F ofFig. 1, the parts being separated, as in the previous figure. Fig. 10shows a section taken on line C D of Fig 1 in the position which theparts assume when placed together. Fig. 11 shows a section taken on thesame line with malleable projections for securing the parts togetherturned down in securing them together.

Referring more particularly to the reference-numerals marked on thedrawings in a more particular description of the device, 1 indicates thelink, which consists of the two separable sections 2 and 3. Thesesections are exact duplicates. Each section is provided with an openside, as shown at ain serial No. 433,091. (No model.)

Figs. land 5, and the ends of the links adjacent tof,the opening areprovided with recesses or'hollows, as shown at 4:. The end is alsobeveled from the outside inward at the U shaped point l, as shown at 5in Fig. 1. The oppositeljor body portion of the section opposite to theopen side a. is made full, as shown at 6, to substantially fill the openspace a, and

is provided with a pair of malleable projections 7 7, adapted to engagein the U-shaped ends 4 and be bent into the inclined recess 5 5. Eachsection is also provided at each side of thefull portion 6 with a numberof ratchet or saw shaped teeth, as shown at 8 8, having theirperpendicular faces on the side toward the projection 7.

In the ends of the link adjacent to the open side a are provided notchesor recesses 9 9,-

corresponding in size, shape, and number to the teeth 8 and adapted toreceive them.

Each section of the link is provided on its inner face at the end of thelink with a V- shaped holding projection 10, which conforms in generalshape to the outline of the end of the link and extends up to the middleof the link on the end. On the opposite side of the link is provided adowel groove or depression 11, adapted to receive a dowel projection, as10, the grooves corresponding in shape and size to the said projection.

In use the two sections of links 2 and 3 are placed together, as shown,and after being so placed together the projections 7 7 may be bent intothe inclined groove 5. This being done at each side of the link joinsthe two sections firmly and securely together and makes a link that issubstantially the same as a one-piece link. By bending the projection 7to a perpendicular position the parts of the link can be separated. Thelink can be used as one of a series of similarly shaped and sized linkswithout clinching the projection 7 down, as the size of the openingthrough the complete link will be about such as to hold the two partstogether; but I prefer to use the link with the projection clinchingdown, as in this way it is entirely safe and not liable to becomeseparated.

What I claim as new, and desire to secure by Letters Patent, is

1. Alink formed of two duplicate separable parts, each part having anopening at the side of the link and U-sh'aped or hollow ends 4 at eachside of the opening, and the projections 7 at the opposite side of thelink, adapted to engage in the hollow ends of the separate parts,substantially as set forth.

2. A separable link composed of duplicate parts, each part having anopen side and U- shaped beveled ends at side of the opening in the side,and the malleable projections on the opposite side of the link from theopening and projecting at right angles from the plane of the link andadapted to be bent into the hollowed beveled ends, substantially as setforth.

3. The combination, in the separable link, of the two parts thereof,each part having an open side, and the ends of the part adjacent to theopening being thinner than the body portion and-opposite side of thepart and terminating in the hollowed and beveled end,

malleable projections on the opposite side of the part from the openside, and serrations on the part adjacent to the projections and adaptedto engage in corresponding depressions in the ends of the part adjacentto the open side, substantially as set forth.

4. A link composed of duplicate separable parts, each part having anopen side, locking projections on the parts on the opposite side fromthe open side, adapted to engage the ends of the parts adjacent to theopen side, and dowel projections on the engaging faces of the two partsat the ends of the part, and a corresponding dowel depression in theends of the parts on the opposite sides of the longitudinal central linefrom the dowel projection for receiving the dowel projection,substantially as set forth.

5. Aseparable link consisting of two duplicat-e parts, each part havingan open side and malleable locking projections on the side opposite tothe open side, projecting at right angles from the plane of the link andadapted to engage the ends of the part adjacent to the open sideserrations on the engaging faces of the part adjacent to the malleableprojec tions, and corresponding depressions in the ends adapted toreceive the serration and dowelprojection rib on the engaging face ofthe parts at the end of the part, and a corresponding dowel depressionon the opposite side of the central longitudinal line from theprojection, adapted to receive the projection, substantially as setforth.

In Witness whereof I have aflixed my signature in presence of twowitnesses.
